feat: Add issue reporter floating button (like people-search)

[rayketcham]

Feature

Add a floating action button (FAB) with issue reporter modal to Project Forge, similar to the one in people-search (/opt/people-search).

What people-search has

• Floating action button (bottom-right corner)
• Multi-step modal wizard (Type → Context → Review)
• 7 issue types with color-coded icons
• Auto-detects page context from URL
• Severity selection
• AI-powered issue structuring via Claude API
• GitHub CLI integration for issue creation
• Console error capture

What to build for Project Forge

A vanilla JS implementation (no React) with:

• Floating action button in base template
• Modal with issue type selection, description, severity
• Auto-capture of current page URL and context
• Backend POST /api/issues/report endpoint with Pydantic model
• GitHub CLI integration for issue creation (gh issue create)
• Rate limiting
• Tests for the API endpoint

Scope

Simpler than people-search since project-forge uses plain HTML + vanilla JS, but same core UX: click button → describe issue → submit → GitHub issue created.
